Yes, see the API reference at www.gtk.org and look for signals, you
will find a whole bunch of signal_disconnect functions.

gtk_signal_disconnect is probably what you want, basically you need to 
save the signal id when connecting, so you can tell GTK which signal 
you want to disconnect later on.
